Why do I receive several compiling errors when trying to compile a C++ engine application using the Borland Free Compiler with the MATLAB Compiler?

When I create a C++ engine application and use my Borland Free Compiler to compile it, I receive the following errors:

The compiling errors are coming from the stdlib.h file. This file is supposed to be a standard ANSI C header file, but in Borlands free compiler this is not the case. Explicitly defining the following symbol alleviates the problem:

 #define __STDC__ 1

The _STDC_ symbol is Borland specific and forces standard C.

Note: We have found several similar caveats with the Borland Free Compiler (v5.5). If possible, creating a C engine application will result in fewer compile and link issues.
